DETAILED DESCRIPTION

[0015] As shown in the accompanying drawings, this embodiment provides a water tank lifting durability tester, including a base plate 1, and a support mechanism is arranged on one side of the upper part of the base plate 1, and the support mechanism includes a plurality of support rods 4 and at least one support beam 5.

[0016] A control cabinet 2 is arranged on the other side of the upper part of the base plate 1. The control cabinet 2 is provided with on, off and emergency stop buttons respectively. The control cabinet 2 is also provided with a touch control screen. Various functional parameters are set through the touch screen to adjust the rise time, pressing time, pressing holding time and number of times of the side view to meet various experimental needs.

[0017] A lifting mechanism is connected to the supporting mechanism, and the lifting mechanism includes a mounting beam 6, a rotating screw 7, a moving block 8, and a handwheel 9. The mounting beam 6 is mounted on the supporting beam 5 of the supporting mechanism. The rotating screw 7 can be self-rotatingly mounted on the mounting beam 6. The handwheel 9 is connected to the end of the rotating screw 7. The rotation of the rotating screw 7 is controlled by rotating the handwheel 9. The moving block 8 is threadedly connected to the rotating screw 7. The moving block 8 can move along the screw. The connecting plate 10 is connected to the moving block 8.

[0018] The lifting mechanism is connected to the air valve mechanism via the connecting plate 10. By manually rotating the hand wheel 9, the moving block 8 and the connecting plate 10 are moved up and down along the rotating screw 7 as a whole, so that the lifting mechanism can control the lifting of the air valve mechanism as a whole.

[0019] The air valve mechanism includes an air valve 11 and a push rod 12. The air valve 11 is connected to the connecting plate 10. The air valve 11 is provided with an upper air inlet 13 and a lower air inlet 14 distributed up and down. The push rod 12 is inserted into the air valve 11. The piston block connected to one end of the push rod 12 in the air valve 11 is located between the upper air inlet 13 and the lower air inlet 14. The upper air inlet 13 and the lower air inlet are respectively connected to a solenoid valve. The solenoid valve is connected to an air filter through an air pipe. The air filter is connected to an air pump through the air pipe. The air entering the solenoid valve from the air pump is dried and filtered out of moisture through the air filter, and then the dried air is passed into the solenoid valve (wherein each solenoid valve, air filter and air pump are conventionally connected, so they are not shown in the drawings).

[0020] The bottom of the push rod 12 is connected to the clamp 3 at one end outside the air valve 11. The clamp 3 is manually opened and closed to clamp the sink cover to simulate the action of a person grabbing the sink cover by hand. The clamp 3 is controlled to rise and fall through the air valve mechanism to simulate the action of lifting and resetting the sink cover.

[0021] The solenoid valve is electrically connected to the control cabinet 2, and the switching action of the solenoid valve is controlled by the control cabinet 2: when the clamp 3 needs to rise to simulate the lifting action, the control cabinet 2 controls the solenoid valve connected to the lower air inlet 14 to open, and the lower air inlet 14 takes in air, pushing the push rod 12 to drive the clamp 3 to rise; when the clamp 3 needs to descend to simulate the resetting action, the control cabinet 2 controls the solenoid valve connected to the upper air inlet 13 to open, and the upper air inlet 13 takes in air, pushing the push rod 12 to drive the clamp 3 to descend.

[0022] The operation is roughly as follows:

[0023] Manually clamp the water tank cover and fix it on the fixture 3, manually adjust the lifting mechanism to a suitable position, and turn on the air pump and air filter.

[0024] Use control cabinet 2 to set the rising and falling time and the time for holding the downward pressure, that is, set the opening time of the solenoid valve at the lower air inlet 14 and the opening time of the solenoid valve at the upper air inlet 13 respectively, to ensure that the tester can complete five rises and falls within 60 seconds and ensure that the error does not exceed plus or minus one time.

[0025] After completing the operations required by the experiment, check the air tightness of the sink cover and the sink body, and whether the sink cover is damaged or deformed.

[0026] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
